Local know-how
Scuba Diving in Tamarindo, honestly
Most local dive operators run trips to the Catalina Islands, where divers regularly see schools of rays, moray eels, and big groupers. Visibility varies with season and swell — ask the shop about recent conditions before you book.
First-timers can do a Discover Scuba mini course in a day, and several shops run full Open Water and Advanced certifications across multiple days. If you're already certified, bring your card; if you haven't dived in a while, a half-day refresher is a common and worthwhile option.
Before you book
- Bring your certification card if you're a certified diver
- Book multi-day courses early in your trip so weather days don't derail them
- Ask about recent visibility — conditions change with season and swell
- Surface intervals matter: don't schedule a dive within 18–24 hours of your flight home
